While trying to get my remoteproc driver work with this I uncovered a problem
with this approach.

mips-gic doesn't store the actual hwirq in the irq_data. It uses
GIC_SHARED_TO_HWIRQ() and GIC_HWIRQ_TO_SHARED() to add and remove an offset.
Why can't MIPS store the real hwirq number in irq_data?


I'm wary of ending up in inconsistency hell where some functions need to deal with raw hwirq and others with translated ones.

I will give this a go first and see if it gets really ugly.

Thanks,
